Looking for someone available Fridays 3:15-5pm during school/term from January

This is for a couple hours childcare work:
- pick-up my boys 8 and 9 years old from Wix school in Clapham at 3:15,
- cross the common with them to take them home near Clapham South
- give them snack
- quick homework if time allows and then
- drop them by 5pm at a martial arts school near broomwood road (between the commons)
